Hi, I have an Intel Wireless-AC 9462 and I'm trying to get it working under Qubes OS (in a Xen HVM domain). The driver fails when I try to bring the network up: [ 26.012784] iwlwifi 0000:00:07.0: FW error in SYNC CMD RFH_QUEUE_CONFIG_CMD [ 26.012817] CPU: 0 PID: 1187 Comm: ip Not tainted 5.6.3-1.qubes.x86_64 #1 [ 26.012833] Hardware name: Xen HVM domU, BIOS 4.13.0 03/11/2020 [ 26.012848] Call Trace: [ 26.012860] dump_stack+0x66/0x90 [ 26.012884] iwl_trans_pcie_gen2_send_hcmd+0x405/0x410 [iwlwifi] [ 26.012902] ? finish_wait+0x80/0x80 [ 26.012918] iwl_trans_send_cmd+0x51/0xb0 [iwlwifi] [ 26.012938] iwl_mvm_send_cmd+0x1b/0x40 [iwlmvm] [ 26.012955] iwl_configure_rxq+0x141/0x1b0 [iwlmvm] [ 26.012972] iwl_mvm_up+0x422/0x960 [iwlmvm] [ 26.012989] __iwl_mvm_mac_start+0x26/0x1d0 [iwlmvm] [ 26.013006] iwl_mvm_mac_start+0x24/0x40 [iwlmvm] [ 26.013035] drv_start+0x43/0xf0 [mac80211] [ 26.013058] ieee80211_do_open+0x219/0x8e0 [mac80211] [ 26.013082] ? ieee80211_check_concurrent_iface+0x14f/0x1c0 [mac80211] [ 26.013102] __dev_open+0xe0/0x170 [ 26.013112] __dev_change_flags+0x1a1/0x200 [ 26.013124] dev_change_flags+0x21/0x60 [ 26.013135] do_setlink+0x861/0x9b0 [ 26.013148] __rtnl_newlink+0x5d1/0x9a0 [ 26.013163] rtnl_newlink+0x44/0x70 [ 26.013172] rtnetlink_rcv_msg+0x2cb/0x380 [ 26.013184] ? rtnl_calcit.isra.0+0x110/0x110 [ 26.013197] netlink_rcv_skb+0x75/0x140 [ 26.013208] netlink_unicast+0x199/0x240 [ 26.013219] netlink_sendmsg+0x243/0x480 [ 26.013231] sock_sendmsg+0x5e/0x60 [ 26.013243] ____sys_sendmsg+0x21b/0x290 [ 26.013253] ? copy_msghdr_from_user+0xe1/0x160 [ 26.013267] ___sys_sendmsg+0x9e/0xe0 [ 26.013280] __sys_sendmsg+0x81/0xd0 [ 26.013291] do_syscall_64+0x5b/0x1c0 [ 26.013304] entry_SYSCALL_64_after_hwframe+0x44/0xa9 [ 26.013317] RIP: 0033:0x7d18f2170b87 [ 26.013331] Code: 64 89 02 48 c7 c0 ff ff ff ff eb bb 0f 1f 80 00 00 00 00 f3 0f 1e fa 64 8b 04 25 18 00 00 00 85 c0 75 10 b8 2e 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 51 c3 48 83 ec 28 89 54 24 1c 48 89 74 24 10 [ 26.211994] RSP: 002b:00007fff536402c8 EFLAGS: 00000246 ORIG_RAX: 000000000000002e [ 26.212016] RAX: ffffffffffffffda RBX: 0000000000000000 RCX: 00007d18f2170b87 [ 26.212035] RDX: 0000000000000000 RSI: 00007fff53640340 RDI: 0000000000000003 [ 26.212055] RBP: 000000005e943910 R08: 0000000000000001 R09: 0000000000000230 [ 26.212074] R10: 0000000000000040 R11: 0000000000000246 R12: 0000000000000001 [ 26.212092] R13: 00007fff53640b10 R14: 00007fff53640410 R15: 00005c5e4aef8020 [ 26.212170] iwlwifi 0000:00:07.0: Failed to configure RX queues: -5 [ 26.212193] iwlwifi 0000:00:07.0: Hardware error detected.

The firmware version is: 48.4fa0041f.0 QuZ-a0-jf-b0-48.u I can provide full dmesg.log, and a trace (output of 'trace-cmd record -e iwlwifi -e mac80211 -e cfg80211 -e iwlwifi_msg'). I'm not sure if I am allowed to send attachments to this list? As a workaround, I tried to remove the call that was apparently causing the crash (iwl_configure_rxq), see patch below. This actually worked, and I can use wifi now. I'm not sure if it's related, but Qubes OS users report similar crashes when trying to run Intel AX200 [1] [2].
