Драйвера установились (ОС AstraLinux SE 1.5 ядро 4.2.0-23-generic) и заработали на серверах HP и в виртуалке. Но есть проблема с серверами DEPO. Схема такая: Соединяем два порта NPort перемычкой (P1 <-> P4). В одном терминале пишем в порт: echo "123" >> /dev/ttyr00 Проходит нормально, индикаторы на NPort моргают. В другом терминале читаем из порта: cat /dev/ttyr03 В итоге cat зависает, а в первом терминале получаем: Oct 20 16:32:17 astra kernel: [ 2115.725171] BUG: unable to handle kernel paging request at 0000000002010e60 Oct 20 16:32:17 astra kernel: [ 2115.725194] IP: [<ffffffff813748b6>] memcpy_erms+0x6/0x10 Oct 20 16:32:17 astra kernel: [ 2115.725211] PGD 35ca9067 PUD 35ca1067 PMD 35eff067 PTE 800000025ecd1867 Oct 20 16:32:17 astra kernel: [ 2115.725231] Oops: 0001 [#1] SMP Oct 20 16:32:17 astra kernel: [ 2115.725242] Modules linked in: nls_iso8859_1 uas usb_storage parport_pc ppdev lp parport rfcomm bnep bluetooth npreal2(O) joydev input_leds mei_me shpchp mei acpi_als ipmi_ssif kfifo_buf ipmi_si ipmi_msghandler industrialio intel_lpss_acpi intel_lpss acpi_power_meter 8250_fintek pinctrl_sunrisepoint pinctrl_intel mac_hid acpi_pad parsec(O) uvesafb hid_generic usbhid ast syscopyarea sysfillrect sysimgblt ttm drm_kms_helper drm igb dca ptp pps_core i2c_algo_bit ahci libahci i2c_hid hid video digsig_verif(O) Oct 20 16:32:17 astra kernel: [ 2115.725402] CPU: 0 PID: 3489 Comm: npreal2d Tainted: G O 4.2.0-23-generic #28astra39 Oct 20 16:32:17 astra kernel: [ 2115.725422] Hardware name: DEPO Computers Super Server/X11SSM-F, BIOS 1.0b 12/29/2015 Oct 20 16:32:17 astra kernel: [ 2115.725440] task: ffff880035f24980 ti: ffff880035f252e8 task.ti: ffff880035f252e8 Oct 20 16:32:17 astra kernel: [ 2115.725457] RIP: 0010:[<ffffffff813748b6>] [<ffffffff813748b6>] memcpy_erms+0x6/0x10 Oct 20 16:32:17 astra kernel: [ 2115.725477] RSP: 0018:ffff880035e63dc0 EFLAGS: 00010282 Oct 20 16:32:17 astra kernel: [ 2115.725489] RAX: ffff88026bf2bc20 RBX: 0000000000000000 RCX: 0000000000000001 Oct 20 16:32:17 astra kernel: [ 2115.725505] RDX: 0000000000000001 RSI: 0000000002010e60 RDI: ffff88026bf2bc20 Oct 20 16:32:17 astra kernel: [ 2115.725521] RBP: ffff880035e63e28 R08: 0000000000000001 R09: 0000000000000001 Oct 20 16:32:17 astra kernel: [ 2115.725537] R10: ffffffff81461744 R11: 0000000000000246 R12: 0000000002010e60 Oct 20 16:32:17 astra kernel: [ 2115.725553] R13: ffffffffc0434c10 R14: 0000000000000000 R15: 0000000000000001 Oct 20 16:32:17 astra kernel: [ 2115.725569] FS: 00007fa9dbea1740(0000) GS:ffff880277800000(0000) knlGS:0000000000000000 Oct 20 16:32:17 astra kernel: [ 2115.725587] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 Oct 20 16:32:17 astra kernel: [ 2115.725600] CR2: 0000000002010e60 CR3: 000000007735f000 CR4: 00000000003606f0 Oct 20 16:32:17 astra kernel: [ 2115.725617] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 Oct 20 16:32:17 astra kernel: [ 2115.725632] DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400 Oct 20 16:32:17 astra kernel: [ 2115.725649] Stack: Oct 20 16:32:17 astra kernel: [ 2115.725654] ffffffff81461a14 ffff880035e63e18 0000000000000001 ffff88026bf2bc00 Oct 20 16:32:17 astra kernel: [ 2115.725675] 0000000000000001 0000000000000292 ffff88026bf2bc20 ffffffffc0434c10 Oct 20 16:32:17 astra kernel: [ 2115.725696] ffffffffc0434c08 ffffffffc0434c10 0000000002010e60 ffffffffc0434f18 Oct 20 16:32:17 astra kernel: [ 2115.725718] Call Trace: Oct 20 16:32:17 astra kernel: [ 2115.725726] [<ffffffff81461a14>] ? tty_insert_flip_string_fixed_flag+0x94/0x100 Oct 20 16:32:17 astra kernel: [ 2115.725746] [<ffffffffc0482766>] npreal_net_write+0xc6/0x150 [npreal2] Oct 20 16:32:17 astra kernel: [ 2115.725763] [<ffffffff81250e2d>] proc_reg_write+0x3d/0x70 Oct 20 16:32:17 astra kernel: [ 2115.725777] [<ffffffff811e6658>] __vfs_write+0x18/0x40 Oct 20 16:32:17 astra kernel: [ 2115.725790] [<ffffffff811e788c>] vfs_write+0x12c/0x210 Oct 20 16:32:17 astra kernel: [ 2115.725803] [<ffffffff811e7c2f>] SyS_write+0x4f/0xa0 Oct 20 16:32:17 astra kernel: [ 2115.725817] [<ffffffff8178caf6>] entry_SYSCALL_64_fastpath+0x16/0x79 Oct 20 16:32:17 astra kernel: [ 2115.725832] Code: 90 90 90 90 90 eb 1e 0f 1f 00 48 89 f8 48 89 d1 48 c1 e9 03 83 e2 07 f3 48 a5 89 d1 f3 a4 c3 66 0f 1f 44 00 00 48 89 f8 48 89 d1 <f3> a4 c3 0f 1f 80 00 00 00 00 48 89 f8 48 83 fa 20 72 7e 40 38 Oct 20 16:32:17 astra kernel: [ 2115.725941] RIP [<ffffffff813748b6>] memcpy_erms+0x6/0x10 Oct 20 16:32:17 astra kernel: [ 2115.725956] RSP <ffff880035e63dc0> Oct 20 16:32:17 astra kernel: [ 2115.725964] CR2: 0000000002010e60 Oct 20 16:32:17 astra kernel: [ 2115.725973] ---[ end trace d01bc76cbc5015cd ]--- Может кто сталкивался с таким?
